[Discuss-gnuradio] fm, vector_source

[cswiger]

Hello -

Q: How is gr.frequency_modulator_fc() used? I see it takes
a 'sensitivity' arg, a float signal in and produces a complex out.
What is being frequency modulated how?

Also, I see gr.vector_source_x() is a powerful tool for generating
mathematically calculated or arbitrary waveforms.

a = range(-450,450,1)
gr.vector_source_s(a, 1)

Voila, a ramp.
